BuzzFeed: "The secret to the grassroots success lies, in part, in the unique national structure and scrupulous record-keeping of the Utah-headquartered Church of Jesus Christ of Latter-day Saints. While the church itself is politically neutral, it contains the structural groundwork for one of the most organized and effective voting blocs in the country -- something Romney is poised to capitalize on."
"In contrast with most other religions in the country, the Mormon Church is nationally organized in a strict, top-down fashion, like a corporation. Every congregation in the U.S. reports back to church headquarters in Salt Lake. Whenever an individual is baptized -- either as a child or as a convert -- local ministers take down the person's name, address, phone number, and e-mail address... The church expressly forbids using these directories for non-religious
purposes, but that doesn't deter many politically active Mormons from
working their ward lists to get out the vote. Reports abound of members
blasting out congregational e-mails soliciting support for partisan
causes and candidates."
